The skill facts display what I assume are the correct values (240 for geyser and 450 for healing rain), but the actual water field AoEs effects are too small (180 for geyser, 360 for healing rain).
Also, the Static Field skill fact is incorrect – it displays 180 radius when the actual radius of the effect is 240. In addition, while Frozen Ground’s skill fact is consistent with it’s actual effect (300), but I believe should have been increased with the June 23 patch that made Blasting Staff baseline (should be 360).
